Description

The 21504-00-40-10-02 is an 8 mm standard mount proximity probe belonging to the Bently Nevada 7200 series transducer system. This specific configuration features a 0.0 mm unthreaded length (Option 00), a 4.0 in case length (Option 40), a 1.0 m total cable length (Option 10), and includes a miniature male coaxial connector (Option 02). Engineered for non-contacting displacement measurement, this probe is used in machinery protection applications such as monitoring shaft radial vibration, axial position, and rotor stability on rotating equipment like steam turbines, compressors, and centrifugal pumps. The 7200 series proximity transducer system operates on the eddy current principle to detect static and dynamic distances between the probe tip and the observed conductive target. This system is compatible with 3300 and 9000 series monitoring systems and offers an 80 mil (2.0 mm) linear measuring range with a scale factor of 200 mV/mil (7.87 V/mm). The 8 mm probe construction utilizes polyphenylene sulfide (PPS), a high-performance plastic designed to withstand demanding industrial environments including moisture and chemical exposure.

What does the 00 option mean in the 21504-00-40-10-02 part number?

The 00 option indicates a 0.0 mm unthreaded length for the probe body, meaning the threads extend to the base of the probe tip.

Is this probe compatible with 3300 series monitors?

Yes, the 7200 series proximity transducer systems, including the 21504 probe, are compatible with Bently Nevada 3300 and 9000 monitoring systems.

What is the material of the 8 mm probe tip?

The 8 mm probes are constructed of polyphenylene sulfide (PPS), a high-performance plastic suitable for harsh, wet, or chemically active environments.

Does this probe require an extension cable?

Yes, the 21504-00-40-10-02 has a 1.0 m integral cable and typically requires an extension cable to complete the 5-metre or 9-metre transducer system length requirement.
